Issue219

Sets max submissions to 12 every four hours and exempts subscribers from having max submissions per timeframe entirely. I looked at changing the four hour time period to one hour but it would have necessitated a hell of a lot of reskey_vars table changes so we're sticking with four hours for now and I more or less like 12 per. If you think on it and decide it needs to be higher or lower, rock on with your bad self and change it.

Oh, there are a lot of reskey checks in there but the only thing subscribers are getting a complete pass from on this are submissions because any other type of reskey will resolve undef to $check_vars->{subscriberbypass} on account of that key not existing for anything but rkrid 6.
